▎ 摘　　要

NOVELTY - Selective catalytic reduction catalyst preparation involves loading graphene oxide containing groups as a precursor with manganese in graphene solution through a two-step process. The prepared graphene oxide is calcined to form selective catalytic reduction (SCR) catalyst. USE - Method for preparing selective catalytic reduction MnOx/graphene catalyst for use in low-temperature flue gas denitrification system (all claimed). ADVANTAGE - The method prepares the selective catalytic reduction catalyst in a simple manner with unique extension and larger theory ratio area, enhanced active component dispersion, and good low temperature selective catalytic reduction smoke removing effect.
